Open Root V-Groove Weld

11-11-2013, 05:48 PM

Hi,

I have been trying to do a root pass using an E6010 in flat position on a beveled butt joint using 3/8" material (mild steel). I get good penetration on half of the joint, but not the whole pass. I am not sure about how best to move the stick to get the best penetration on the root face. I set the amperage at 75 amps. I have heard of "key holing" but when I try this I burn a hole in the joint. I think it is because I am still not very skillful at controlling the stick. I also don't understand what "whipping" the electrode is.

Search YouTube for whipping stick weld technique. Also how to root pass stick. Just need to practice more when you are able to weld and control your electrode you will be able to run the root nice and clean.

Thanks Anybody for any good Tips!

Ok! Been there-done that! First off-Are you running 1/8 sticks! Your amps will depend on size and welding speed. On 1/8 6010-I like to run them at about 60 amps. Works at my welding speed. You may be running too hot. The 6010 is an aggressive burning electrode!

The "keyhole" is like running a bead on the back side if the base material. You move the puddle forward until you get what looks like the old fashioned key hole-then twitch your wrist forward to let it freeze-then back to form a new puddle.
